Selectively hide volumes on desktop

[Pavel Fedin]

  Hello there!
  I'd like to ask if there is a possibility to selectively hide volumes 
from the desktop. There is an icon called "Root volume" and it annoys me 
because in fact it duplicates "Filesystem" icon in "My computer" (root 
volumes also appears there too).
  I also have a Linux box and "Root volume" doesn't appear there. Can i 
replicate this effect on FreeBSD?
  I guess this depents on whether the volume is mountable by non-root 
users or not. On Linux this can be set individually using "user" option 
in /etc/fstab, on FreeBSD this is set globally for all the system using 
sysctl value. BTW, i think it's bad that root can be unmounted by user.
